Embodiment 1
[0028] Dissolve 0.08mol aluminum nitrate and 1.21g urea in 80ml of deionized water, stir vigorously for 20min, then dissolve 0.08mol trisodium phosphate in the above solution, continue stirring for 30min, then transfer the solution to 100ml polytetrafluoroethylene In a stainless steel hydrothermal reaction kettle with ethylene lining, seal it, set the reaction temperature to 150°C, and close the reaction after 35 hours of reaction. When the reaction kettle is cooled to room temperature, use a vacuum filter to separate the white precipitate from the solution, and then put The white precipitate was washed with ethanol and distilled water. The obtained samples were dried at 60 °C for 24 h. Gained sample is done X-ray diffraction analysis (results such as figure 1 shown) and transmission electron microscopy analysis (results are shown in figure 2 shown). This embodiment makes nano-rod AlPO 4 -15 powder.
[0029] from figure 1 It can be seen that the XRD pattern of the sampl...
Embodiment 2
[0032] Dissolve 0.16mol aluminum nitrate and 2.0g urea in 80ml of deionized water, stir vigorously for 20min, then dissolve 0.16mol trisodium phosphate in the above solution, continue stirring for 30min, then transfer the solution to 100ml polytetrafluoroethylene In a stainless steel hydrothermal reaction kettle with ethylene lining, seal it, set the reaction temperature to 150°C, and close the reaction after 30 hours of reaction. When the reaction kettle is cooled to room temperature, use a vacuum filter to separate the white precipitate from the solution, and then put The white precipitate was washed with ethanol and distilled water. The obtained samples were dried at 60 °C for 24 h. The obtained samples were analyzed by transmission electron microscope (results are as follows: image 3 shown).
Embodiment 3
[0034] Dissolve 0.16mol aluminum nitrate and 2.0g urea in 80ml of deionized water, stir vigorously for 20min, then dissolve 0.16mol trisodium phosphate in the above solution, continue stirring for 30min, then transfer the solution to 100ml polytetrafluoroethylene In a stainless steel hydrothermal reaction kettle with ethylene lining, seal it, set the reaction temperature to 150°C, and close the reaction after 50 hours of reaction. When the reaction kettle is cooled to room temperature, use a vacuum filter to separate the white precipitate from the solution, and then put The white precipitate was washed with ethanol and distilled water. The obtained samples were dried at 60 °C for 24 h. The obtained samples were analyzed by transmission electron microscope (results are as follows: Figure 4 shown).
[0035] from Figure 4 It can be seen that the reaction time has a certain influence on the rod-shaped growth. When the reaction time is short, the obtained particles are tiny. A...
